Energy conservation and information conservation

Click For Summary
SUMMARY

The discussion centers on the conservation of information during energy conversion, particularly in the context of black holes and quantum states. Participants reference the black hole information paradox, highlighting the debate between Stephen Hawking and Leonard Susskind regarding whether information is lost in black holes. It is established that Susskind's conclusion, which asserts that information is not lost, has gained acceptance. The conversation also touches on the implications of particle-antiparticle annihilation and the nature of quantum information.

PREREQUISITES
  • Understanding of quantum information theory
  • Familiarity with black hole physics
  • Knowledge of particle-antiparticle interactions
  • Basic concepts of gravitational waves and their properties
NEXT STEPS
  • Research the black hole information paradox in detail
  • Study the implications of Hawking radiation on information conservation
  • Explore quantum information storage in quantum states
  • Investigate the role of gravitational waves in modern physics
USEFUL FOR

Physicists, astrophysicists, quantum information theorists, and anyone interested in the fundamental principles of energy and information conservation in the universe.

How is information conserved when one form of energy is converted to other?
Like how a black hole's gravitational energy is used to create photon pairs near the event horizon, what happens to the information in the gravitational wavepackets (gravitons?) and how is it not lost?

As I explained in your other thread, this "particle pair" thing doesn't stand up to detailed scrutiny.

What about annihilation? What happens to the quantum information in a particle and its antiparticle when they annihilate to give rise to a photon pair?

I don't even understand what "information" means in that context. I'm not suggesting you've asked a bad question, only that I'm have no knowledge that would help. I'm sure someone here will.

What do YOU see as "information" in this context?

I'm talking about quantum information, that's stored in/as quantum states, information that can apparently be lost to black holes.

I believe that the black hole information loss war between Hawking and Susskind was resolved in Susskind's favor, with Hawking conceding the correctness of Susskind's conclusion that information is NOT lost in a black hole. I really know next to nothing about all this stuff.

Your question is known as the black-hole information problem. Wikipedia offers several candidates for possible answers, each with its advantages and disadvanateges:
